What if

the light of the Sun was disappearing

GranPa and his young accomplice Zoe lead a peaceful life in their ranch, up until the day when their tranquil existence is disturbed by a strange event: the light of the Sun grows dimmer, as if it is disappearing. No time to waste, our two heroes rush off on a race against time to save the sunlight.

As a retired scientist, GranPa spends his time fishing, guzzling eucalyptus sticks, and discussing the mysteries of the universe for hours on end. Yes, he is passionately interested in astronomy – so what could be better for talking about light?


This little 10 year old dingo regularly comes visiting GranPa's ranch. If the two of them hang out so much together, it’s because they both share the same love of science.


This is Bogbog. He’s a teenage alien who hasn’t found anything better to do than attack our planet. He’s a long-time enemy of GranPa, and we can imagine them fighting, their historic struggles, their endless thirst for vengeance, a long list of upset plans.

Science for all

Waves, colors, heat, velocity. Light covers many scientific basic knowledges. As a scientific approval we have worked with Stéphanie Escoffier, Director of Research with the CNRS at the Marseilles Centre of Particule Physics, and member of the SDSS project.

A 3D Emotion / Mediastro Promotion co-production

3D Emotion (director / co-producer)

Created in September 2001 by Vincent Arrouy and Stéphane Bertrand, the 3D emotion studio began creating shows for planetariums in 2005 with The Race to Earth. Since that date six other films have been made, including Polaris and Lucia, both international successes.With GranPa & Zoe, the studio has signed a creation for which it is both director and co-producer.

Mediastro Promotion (co-producer)

Médiastro Promotion is an association which uses shows to help a broad audience discover scientific knowledge in astronomy. With Polaris and Lucia, and now GranPa & Zoe, Médiastro Promotion aims to provide planet­ariums with high quality full dome shows, where science is backed up by action – for the greater pleasure of audiences of every age.

This is the first time a show of this kind is on offer to planetariums. It was a new challenge for us, and we are proud to have stepped up to meet it. We offer our film in a final 8k stereoscopic version.
